JACOB K. ALTEM'U'S, OLE PHILADELPHIA, PENNSYLVANIA;

Application filed September 22, 1926.

This invention relates to machines for winding yarn upon conical or other cores or foundations and particularly to machines in which the yarn guide is raised and lowered to build the layers of the yarn upon the rotating cone and in which gain movements are imparted to the yarn guide during the raising and lowering thereof, and in which the gain movements of the yarn guide are arrested immediately upon the breakage of the yarn being delivered to the cone or the discontinuance of the feeding of the yarn, a type of such machines being shown and described in my Letters Patent No. 1,498,721, date May 13, 1924.

An object of my present invention is to improve the means for arresting the gain movements of the yarn guide when the yarn breaks or its feed is discontinued for other causes, by the provision of a novel and inexpensive mechanism whlch will take care of Weak or tender yarns'iand operate efliciently on all counts of yarns.

Another object of the invention is to provide a novel knot or slub catching device which is constructed and arranged relatively to the gain guide and the winding spindle so that knots or slubs in the yarn will be arrested and so that the wear of the yarn on the device will be distributed over a large area, thereby prolonging the life of the device.

The invention consists of the elements and the combinations of them hereinafter described and claimed.

In the accompanying drawings, illustrating the invention, i

Figure 1 is a top view of a portion of yarn winding machine embodying my invention, showing a cone on the winding spindle and a quantity of yarn wound upon the cone.

Figure 1 is a detail of the throwout arm.

Figure 2 is a front view of the parts shown in Fig. 1.

Figure 3 is a view similar to Fig. 2, partly broken away and the cone removed from the spindle.

Figure 4 is an end view of the two bars which form the yarn passage of the knot catcher.

Referring to the drawings, 5 designates a winding spindle which is mounted to r0 tate in a bearing 6 formed on a bracket 7 YARN-WINDING- MACHINE.

which forms a part of the main frame or support of the machine.

A builder screw 24 is provided which rises fixedly from a plate 25 secured on a vertically reciprocable builder rail 15.

Rotatably mounted on the screw 24 is a nut gear 26 having a downwardly extending sleeve 27 surrounding the screw 24 and having a plate or arm 28 engaged with the thread of the screw 24 to cause upward movement of the nut gear 26 whenit is turned in the direction of the arrow in Fig. 1. One end of the plate 28 is pivoted at 29 to the gear 26 and the other end thereof is held normally in an engagement with the screw 24 by a spring 30 connecting the plate 28 and gear 26. a

An elongated driving gear or pinionv35 is provided to turn in suitable bearings on the machine frame; and a guiding post 44 is also provided which rises fixedly from the plate 25; the builder screw 24, the driving gear 35 and the guiding post 44 all being ar ranged onparallel vertical axes as illustrated.

The parts thus far described correspond with the similarly numbered parts in my aforesaid Patent No. 1,493,721, and they are supported and operated. by the mechanism of the winding machine the same as the same parts shown and described in my said patent and, therefore, no detail description thereof is deemed necessary herein.

The nut gear 26 carries an arm or carrier 2 having a sleeve 3 which surrounds the gear sleeve 27 in a manner to permit the gear sleeve to turn therein. The guiding post 44 extends through an opening in the carrier 2 and guides it vertically when it is raised and lowered by and with the nut gear 26, and which prevents the carrier from being turned by the nut gear 26.

F ulcrumed at 4 on the carrier 2 is a yarn guiding lever 8 carrying a gear wheel 9 on one end portion thereof and carrying a yarn guide 10 on the opposite end portion thereof. The gear wheel 9 is constantly in mesh with the nut gear 26, and, it is adapted to be moved into engagement with the driving gear 35 when the lever 8 is moved to the position shown by full lines in Fig. 1, and

out of mesh with the driving gear 55 when the lever 8 is moved to the position shown by dot-and-dash lines in Fig; h The lever Sis provided with two spaced stop projections 11 and 11 adapted to engage an interposed stop projection 12 on the carrier 2 and limit the movement of the lever 8 when it reaches either the full line position or the d-ot-and-dash line position shown in Fig. 1.

The carrier 2 is provided with a projecting arm 13 carrying a knot catcher and yarn cleaning device, the'parts of which are constructed and arranged as follows:

Extending through a slot 14; in a bracket 16 is a screw 17 which is screwed into the arm 13 and secures the bracket 16 thereon. One end of the bracket 16 has a head 18 formed thereon from'which project two parallel bars 19 forming a yarn passage 20 between them. These bars 19 are each provided with a round end portion 21 fitted within a bore in the bracket head 18, and the bracket head 18 is provided with set screws 22 for securing the round end portions 21 to the head 18. The bars 19 are made from stock bars originally square in cross section which are turned to form the round projections 21, which are left square fora short distance from the head 18, and, which have the remaining free portions cut out at 23 to provide opposing walls for the yarn passage 20, which flare outwardly from the entrance to the passage. The yarn passes through the passage 20 in the direction of the arrows in Figs. 1 and 4, and the surfaces 31 of the bars 19 present abrupt obstruction walls to a knot or slub on the yarn passing between the bars 19 and effectually interrupt or stop the forward movement of the knot or slub.

The winding spindle 5 is adapted to carry and rotate a cone 32 or other suitable foundation upon which the yarn is to be wound, and I have herein illustrated the cone applied to the spindle 5 and carrying a quantity of yarn 33. The knot catcher is located 4 between the'yarn guiding lever 8 and the cone 32, and the outer end portion 34 of the yarn 33 wound upon the cone 32 extends from the cone through the yarn passage 20 of the knot catcher, and through the yarn guide 10 on the lever 8, and then up wardly from the yarn guide 10 to the source of supply for the yarn being fed to the cone during the winding operation. The long narrow passage 20 of the knot catcher extends horizontally and transversely of a line extending between the yarn guide 10 and the 'con'e'32, .so that when the knot catcher and the yarn gulde are raised and lowered by and with the nut gear 26 they will raise and lower the yarn 33, and, so that the yarn 33 may work back and forth within and longitudinally of the yarn passage 20 as the yarn 33, being fed to the cone 32, moves toward and from the axis of rotation of the cone as shown by full lines and by dotand-dash lines in Fig. 1. Thus a wide range of wearing surface of the bars 19 forn'iing the yarn passage 20 is presented to the yarn passing between the bars 19 to prevent the cutting of the bars by the yarn.

The opening between the bars 19 forming the yarn passage 20 may be varied for different counts of yarn by loosening the set screws 22 and turning the bars 19 slightly on the axes of their round portions 21 and then tightening screws 22.

During the operation of the machine the winding spindle5 and driving gear 35 are rotated and the builder rail 15 is raised and lowered as described in my aforesaid Letters Patent; and the yarn 33 is drawn down from a source of supply above the yarn guide 10 to and through the yarn guide 10 and through the knot catcher and is wound upon the cone 32. At each up and down stroke of the builder rail 15 the yarn guide and knot catcher are raised and lowered to cause the yarn 33 to be wound in spiral-like superposed layers upon the cone 32.

As the layers of yarn are thus wound upon the cone 32, the nut gear 26 is periodically moved upwardly on the builder screw 24- relatively to the builder rail 15 to impart the upward gain movements to the yarn guide and knot catcher relatively to their constant up and down move'ments by the builder rail 15 to build the successive layers of yarn upon the cone 32 and upon each other.

The yarn 33 passing through the guide 10 and through the knot catcher draws upon the guide 10 and maintains the. lever 8 in the position shown by full lines-in Fig. 1 with its stop projection 11 in an engagement with the stop projection 12 of the carrier 2 and with the gear wheel 9 in mesh with the driving gear 35, during the winding operation; and, should the yarn 33 run out or break due to the engagement of a knot or slub with the knot catcher or for any other 1 their up and down movement-s by the build-er l rail 15. so that after the broken yarn has been repaired or a fresh strand of yarn has been run through the guide 10 and the knot catcher to the cone 32fthe repaired or fresh strand will draw the lever 8 back to the position shown by full llDQS'HI Fig. 1, and thereby cause it to resume its gain movements under the influence of the gearing between the driving gear 35 and the nut gear 26 at the: same position with respect to the Lit) yarn layers on the cone 32 where the gain movements were discontinued. \Vhen the lever 8 moves to the position shown by dotand-dash lines in Fig. 1 as just described, its further movement is arrested by the engagement of its stop projection 11 with the stop projection 12 of the carrier 2.

It will be observed that the yarn guiding [ever 8 is fulcrumed on the carrier 2 between the axis of rotation of the nut gear 26 and the axis of rotation of the gear wheel 9 and that. the lever 8 is fulcrumed on an axis which is closer to the axis of the driving gear 35 than is the axis of the builder screw 24, and also that the distance between the lever fulcrum l and an axis of the gear wheel 9 is much less than the distance between the lever fulcrum at and the yarn guide 10 carried by the lever. This construction -maintains the gear wheel 9 in constant and proper operating relation with the nut gear 26 and permits it to be moved into and out of mesh with the driving gear 35, and, at the same time provides a leverage for moving the gear wheel 9 which will permit weak and tender yarns to maintain it in mesh with the driving gear 35.
